ALOIS STEINIIAUSER, OF FALL RIVER, MASSACHUSETTS, ASSIGNOR OF ONE- HALF TO DAVID FULLER, OF SAME PLACE.

SIZING COMPOUND.

SPECIFICATION forming part of Letters Patent No. 469,954, dated March 1, 1892. Application filed April 27, 1891. Serial No. 390,677. (No specimens.)

To all whom it may concern:

Be it known that I, ALOIS STEINHAUSER, a subject of the Emperor of Austria-Hungary, and a resident of Fall River, in the county of Bristol and State of Massachusetts, have in vented certain new and useful Improvements in Sizing Compounds, of which the following is a specification.

My invention refers to an improved cointo pound to be added to sizing for cotton thread or yarn or similar articles for the purpose of rendering the yarn more pliable, softer, and stronger and causing the sizing to adhere better to the thread. For this purpose I prepare IS a mixture of tallow, common washing-soap,

preferably soda, soap, glycerine, and gumarabic or equivalent gum, to which I add, by preference, sodium chloride, magnesium sulphate, and potash, or any one or more of these salts. Boil the mixture, 'together'with some water, until a uniform mass is formed and the excess of water is evaporated, and then cast the compound into suitable vessels.

In practice I use, by preference, about the 2 5 following proportions, by Weight, of the materials mentioned, namely: tallow, twenty-five to thirty parts; soap, fifteen parts; glycerine and gum-arabic, one part each; magnesium sulphate, two parts; sodium chloride and pot- 3o ash,one part each. To this I add some Water and boil the mixture until a homogeneous mass is formed and the surplus of water is evaporated, whereupon the mass is poured into suitable vessels for the market and forms an article of trade to be incorporated into ordinary sizing While I hot. It requires about one pound of this compound for sizing prepared from twenty pounds of starch and forty gallons of water.

Gum-arable causes the sizing to stick bet- 4o ter to the thread, and the glycerine and the salts retain moisture and prevent hardening of the sizing. Sizing with this compound added strengthens the thread or yarn and greatly reduces tearing of threads in Weaving.

The compound specified is to form an article of trade to be mixed with common starch in the cotton-mill about in the proportions above set forth.

\Vhat I, claim as my invention is- 1. As an article of manufacture, the hereindescribed compound to be added to starch-sizing, consisting of tallow, soap, glycerine, and gum-arabic, substantially as set. forth.

2. As an article of manufacture, the herein- 5 5 described compound to be added to starch-sizing, consisting of tallow, soap, glycerine, and

- gum-arabic, together with one or more of the ALOIS STEINIIAUSER.
